IMPROVEMENTlN STEAM-RADIATORS. l

Specification forming part of Letters Patent No. 191,156, dated May 22, 1877; application tiled April 6,1877.

To all whom it may commet:

Be it known. that I, ROBERT L. KEnNocn- AN, of Titusville, in the county of Crawford and State of Pennsylvania, have invented a new and useful Improvement in Steam-Radiators; and -I do hereby declare the follow lowing to be a full, clear, and exact description thereof, reference being had to the ac` companying drawing, forming part of this specification, in which- Figure lis a side elevation of a steam-radiator embodying my invention, portions of the base or steam-chamber being `broken away.

.Fig. 2 is a horizontal section of the steamchamber on the. line y y, Fig. l. Fig. 3 is a vertical transverse section on the line z e, Fig.

l; and Fig. 4 is a similar section on the line Like letters refer to like parts wherever they occur.

My invention relates to the constryction of steam heaters or radiators; and consists, first,

4 in a steam-heater having two or more sections or rows of .tubes supplied from independent steam-chambers provided with separate valved inlets, and each having its own outlet, whereby either one or more sections may be employed, according to the radiating or heating surface required; secondly, in a steam heater or radiator having two or more independent sections or rows of tubes, in combination with a single base divided by partitions into a number of independent steam chambers corre spending to the number of independent sections or rows of tubes; thirdly, in combining vwith the base of a steam radiator or heater,v which is divided by partitions into a series of ent constructed, the only manner of reducing their heating capacity is by reducing the head of steam admitted, and when this is done unequal expansion, contained air, and other causes give rise to a continuous hammeringl or noise highly disagreeable and objectionable, and injurious to the heater.

The object of the present invention is to overcome the objection specified as well as others, such as imperfect and complex valves, leakage, Snc., due to the present construction and arrangement of heaters.

I will now proceed toldescribe my invention so that others skilled in the art to which it appertains may apply the same.

In the drawing, A indicates the hollow base of a steam heater or radiator divided by a central longitudinal partition, a, into two steam-chambers, al a2, from each of which rise a series of tubes, b1 b2, surmounted by a cap or slab, b. Each series of radiating-tubes receives steam from and delivers the Water-ot' condensation into its own steam-chamber, and

is independent of any other set or series which may be embraced in the heater. O represents the steam-pipe, which delivers into an inletehamber, c, from whence a series of branches, cl c2, one for each independent steam-chamber, conduct the steam to the series of pipes. The ports or mouths of the inlet branches c1 c2 may be ground or otherwise constructed to form valve-seats e; but, preferably, andespecially where the branches are formed with the base A, the metal is tapped and an independent valve-seat, e1, is inserted, as clearly shown in Fig. 3. Upon the base A, over each independent steam-chamber, and in line with the steam-inlet (or valve-seat 6,) is secured a stuffing-box, E, through which passes a stem, e2, provided with a valve, e3, for controlling the admission of steam. At the opposite end of the base A from the valves, or otherwise arranged, as shall be found most convenient, is a trap, I, for the water of condensation. With this trap each independent steam-chamber, al a2, 8vo., communicates by means of a short pipe or tube, i, which dips into the trap and water therein sufficiently far to close the end of the pipe and prevent the escape ot' of steam from one chamber to another. l'

represents the exit or waste pipe of trap I,

A'rnlvfr Crimen.,

Y section employed receives a full head of steam `out 'noise or hammering or injury thereto;

communicating therewith at a height which will maintain the desired amount of water in the pipe to close pipes 'L'.

Any number ofindependcnt sets or series of tubes with correspondingindependent steamchambers may be embraced in a single heater 5 but each steam-chamber must have its separate valved inlet and separate exit-pipe; and, where the steam-chambers are multiplied, the arrangement and location of the trap I may be varied to meet the' requirements, all of which is within the scope of the present invention. 1

The operation of my devices is as follows: It' the full heating capacity of the radiator is desired, the several valves e3 are moved off their seats, so as to admit a full head of steam toall the steam-chambers throughthe several branches c1 o, Src., the air being expelled, as is usual, where a full head of steam is admitted. The water of' condensation which is deposited in the several independent steamchambers al a?, Src., will enter the common trap through the respective sealed pipes t', and to facilitate the discharge of the water it is desirable to give a slight inclination or slope to the bottom of each steam-chamber.-

When the weather is not sufficiently cold to demand the useof the entire radiating-"sur-l face, but one or more sections or sets of pipes are employed by manipulating the valves of their respective steam-chambers, so as to advmit steam to said sections only, andas eachno hammering or rattling occurs,

The advantages arising from my invention are, first, that any required temperature canl be maintained by means of the radiator withsecondly, complex 'valves for controlling thev admission of steam are avoided; and, thirdly, from the construction of the parts, and `the arrangement ofthe valves within the base of the heater, there is less liability of leakage, and the valves are arranged more conveniently, and are not in the way as when placed upon the steam-pipes, as is usually done.

Having thus described myinvention,l what I claim and desire to secure by `Letters Patent, isL

l. A steam heater or radiator having two or more sectionsl or rows of tubes, each section or row provided with its own steam` chamber, valved inlet, andan outlet, substantially as and for the purpose specified.

2. In a steam heater or radiator having two or mre independent sections, the hollow base divided by a partition or partitions to form corresponding independent steam-chambers, substantially as specified;

3. The combination, in a steam heater or radiator, of the independent sections, and the base composed of a series of independent steam-chambers, each. of said chambers prol vided with au' inlet-valve, substantially as and for the purpose specified.

4. In a steam-heater having an inlet` and valve for closing the same, the independent valve-'seat tapped into' the steam-chamber or hollow base at the mouth of the steam-inlet, substantially as specified.

5. In a steain=radiator, the combination, with a series of independent steauiechambers and corresponding section-s,` of the trap and exit ord-ip' pipes, substantially-as specified.

.6. Ina steam. heater or radiator, the combination,- with a series of independent steamchambers, of the steam-'inlet and branches leading to said chambers, substantially as and for the purpose specified:v

7. In a steam heater or radiator having a steam-chamberor hollcw base, and radiating tubes or sections, the steam-inlet valve l0- cated within the' base or' steam-'chamber,y substantially asv spe'citied.-

Inl testimony whereof I, the said ROBERT L. KERNO'OHAN, have hereunto set my hand.
